I would not run 2 instances at the same time - Jenkins uses file based storage
for configs, etc. and the updates by one would not be seen by the other.
We run tomcat with these settings in the tomcat/bin/start.sh file.
export TOMCAT_LOGS="/var/tomcat/logs"
# Jenkins Settings
CATALINA_OPTS="-DJENKINS_HOME=/var/jenkins/"
# Server Settings
CATALINA_OPTS="$CATALINA_OPTS -server"
CATALINA_OPTS="$CATALINA_OPTS -Djava.awt.headless=true"
# Memory Settings
CATALINA_OPTS="$CATALINA_OPTS -Xms4096m"
CATALINA_OPTS="$CATALINA_OPTS -Xmx4096m"
CATALINA_OPTS="$CATALINA_OPTS -Xmn1024m"
CATALINA_OPTS="$CATALINA_OPTS -XX:PermSize=128m"
CATALINA_OPTS="$CATALINA_OPTS -XX:MaxPermSize=256m"
CATALINA_OPTS="$CATALINA_OPTS -XX:+HeapDumpOnOutOfMemoryError"
CATALINA_OPTS="$CATALINA_OPTS -XX:HeapDumpPath=${TOMCAT_LOGS}"
# Garbage Collection Logging
CATALINA_OPTS="$CATALINA_OPTS -XX:+PrintGCDetails"
CATALINA_OPTS="$CATALINA_OPTS -XX:+PrintGCDateStamps"
CATALINA_OPTS="$CATALINA_OPTS -XX:+PrintHeapAtGC"
CATALINA_OPTS="$CATALINA_OPTS -Xloggc:${TOMCAT_LOGS}/garbage-collection.log"
export CATALINA_OPTS
exec "$PRGDIR"/"$EXECUTABLE" start "$@"

Subject: Upgrade from war file under tomcat to native install
I'm currently running a version of Jenkins under tomcat. I'm pledged by
permgen issues that crash the service regularly. I want to be able to install
a native instance and point it to my Jenkins home on the same server. Can
anybody point me to the steps required to make this a success. Note sure If I
have have the war file running under tomcat and install a native instance on a
windows server at the same time. Not sure if there is port conflict or other
issues that may impact the success of this process.
Any help would be greatly appreciated.
Thanks, Eric
